Same request as Support `@`-mentioning apps which was closed by @jmilas, so I can’t post my use case there. Over in the julia world, we have several bots that perform requested actions when at-mentioned. See e.g. https://github.com/JuliaLang/julia/pull/23046. Now of course the bots can get the comments on repos they care about anyway, but it’s a bit confusing that the @integration[bot] at-mentions the integration user when autocomplete actually suggests that syntax (I noticed this when playing with my new bot because I had actually set up a regular account of the same name before realizing the bot had its own account). I think at the very least it’d be nice to link to the appropriate bot with that syntax.
